the outer end of the fountain pen section which forms one end of the fountain pen barrel or housing. The excess ink thus settling or accumulating in the pocket at the end of the section accumulates on the section stop flange or mouthpiece, making the same unsightly and dirty, so that, when the fountain pen cap is engaged over the section end of the fountain pen barrel or body, the end of the-stop sleeve or shoulder provided in the cap seats directly against the mouthpiece or section flange against the accumulation of excess ink, thereby causing the excess ink not only to dirty the end of the section but also to adhere to the shoulder within the fountain pen cap and thereby dirty, the interior of the cap, as well as the fountain pen section. It will thus be noted that the amount of excess rink is spread around to various parts of the fountain pen and is even carried and spread around the inner walls of the cap, so that, when the same is again inserted over the section and on a portion of the fountainpen barrel, the excess ink is sometimes smeared or applied to the section, so that, when the fountain pen is again put into use, the hands of a user become stained with excess ink, causing the user considerable annoyance and making it necessary not only to wash and clean the various parts of the fountain pen, but also necessitates the washing of the hands of the user as well.

To obviate the above defects in fountain pens of substantially all previous makes, this invention has been devised for the purpose of providing an improved fountain pen section adapted to be used in any make of fountain pen and being so constructed that the outer end of the section affords a pocket or recess for the receiving of excess ink from the feeder bar and-pen point after a fountaln. pen has been 1n use, with said excess ink-receiving pocket being positioned remote from the section stop flange, keepingsaid stop flange absolutely free from excess ink accumulation, i

so that, when a fountain pen cap is engaged over the writing end of a fountain pen,-'the shoulder within thecapisadapted to seat" against a clean stop flange of the section, thereby obviating the spreading of the excess ink to the various parts of the fountain pen.

It is an object of this invention to provide an improved fountain pen section, the outer end of which is provided with a sleeve exten- S1011 PIOJGCtlIlg beyond the cap stop flange of the sectlon and provldmg a recess orpocket for the reception of excess inkflowing back penpoint after a fountain pen has been inuse.

It is also an object of this inventionto provide an improved fountain pen'section, the outer end of which is provided with a recess ing back from the fountain pen feed bar and pen point, with said pocket being remote from the stop flange formed on the section to keep the same clean-and free from ink accumulation, affording a clean seatfor the" stop shoulder provided within pen cap. 7

It is a further object of'thi's invention'to the fountain provide an improved fountain pen section constructed to afford a pocket for the recep tion of excess ink flowing back from the feed bar and pen point of a fountain pen, with said pocket being remote from the fountain pen cap stop flange of the section to afford an parts of the fountain pen and cap are kept clean.

It is-furthermore an object of this invention to provide an improved simplified form of fountain pen section wherein the outer end from the outer end of the'feed bar and the or pocket for the reception of excess ink flow-" improved arrangement whereby the'various on the section against which the shoulder within the fountain pen cap is adapted to seat, thereby obviating the spreading or smearing of the excess ink to parts of the fountain pen with which the hand of a writer is usually brought in contact.

It is an important object of this invention to provide an improved, simplified and inexpensive type of fountain pen sectionwhich is constructed with a special receiving pocket for excess ink returned from the fountain pen feed bar and pen point after the pen has been in use, to obviate the spreading of the returned excess ink accumulation, thereby keeping the various parts of the fountain pen and the interior of the fountain pen cap free :from ink, and furthermore obviating the Staining. of the hands of a user of the fountain pen. 7 Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawing.

The invention (in a preferred form) is i1- lustrated in the drawing and hereinafter morefully described.

. On the drawing:

Figure 1 is an enlarged fragmentary elevational view of the pen point end of a fountain pen equipped with an improved fountain pen section embodying the principles of this invention andshowing the fountain pen cap in position, and partly in section, enclosing the'fountain pen section with the cap shoul- 1 der seating against the section stop flange.

FigureEZ is an enlarged side elevation of an improved fountain pen section embodying the principles of this invention.

Figure 3is a longitudinal sectional view of the fountain pen section, showing a fragmentary portion of a fountain pen feed bar engaged therein and shown in elevation.

Figure 4; is an end View of the improved tounta npen e t n- As shown on the drawing:

The reference numeral 1 indicates a fountain pen cap provided with an internal threaded section at 2, a short distance from the open end] thereof, and having rigidly segaged, over one end of a fountain pen barre-l or housing 5, the outer end of which is externally threaded at 6 for the reception of the V threaded section 2 formed within the cap 1, as

clearly illustrated in Figure 1. The threaded end of; the fountain, pen barrel or housing 5 is 1 also internally threaded to receive the externally threaded shank T of an improved fountain pen section embodying the principles of c this invention. The section shank '7 is provided at its outer end, with a plurality of equidistantly spaced openings or notches. 8 prothe interior of the fountain pen barrel 5, in certain types of fountain pens, to be admitted into the feed chamber 9 of the section shank 7 The threaded shank 7 is integrally formed on the inner end of an externally tapered section body 10, the interior of which is provided with an axial passage 11, one end of which terminates, in the chamber 9 of, the shank portion 7, while the opposite end communicates with the inner end of a'surplus or excess ink-receiving pocket or recess 12 provided in an extension sleeve or collar 13 which is integrally formed on the outer end of the section body portion 10 to the outside of a stop ring or flange 14 integrally formed externally on the outer end of the body portion 10 where itjoins the extension sleeve or collar 13. When the capv 2 is engaged on the barrel 5, as indicated in Figure 1, the shoulder l provided within the cap is adapted to seat against the stop flange or ring 14 of the sec tion, with the sleeve or collar 13 projecting into the end of the sleeve 3 secured within the cap 1, so that the shoulderv 1- of the cap doesnot come into. contact with the endiof tightly within the passage 11 of the section body 10, as illustrated in Figure 3, and terminates at the recess or pocket 9 provided in the section shank 7 Integrally formed on the outer end of the feed bar shank 1 5. is a feed bar passaged head 16 which projects through the excess ink passage or chamber 12and is partially covered by a pen point 17 the shank end of which is adapted'to be rigidly secured in the body portion 10 of the fountain pen section. l

The improved fountain en section, which is constructed to provide t e pocket or recess for the receptionof excess or'return ink from the fountain pen point and the feedbar,

is adapted for use on any type of fountain pen and provides an ink guard arrangement whereby the ink pocket is positioned remote from the stopflange 14 of the section, sothat the shoulder provided within the fountain pen cap 1 is adapted always to seat against a dry and clean flange or stop ring, thereby affording an arrangement whereby the interior of the cap and the exterior of the section are keptclean and free from excess ink, since the '-l end of the-ink guard extension sleeve orcollar 13- which forms the housing fort-he excess ink recess or pocket fits into the cap liner sleeve 3 and is not in direct contact with the cap stop shoulder.

The pocketed ink guard extension 13,.provided onthe end of the fountain pen section beyondthe stop flange or ring 1 1, provides an improvement which obviates any tendency of "tflClQClfQl, thepurpose of permitting ink from p fountain pen. The feed bar shank 15 seats 9 excess. inkreturned. from the pen. pointzanda the feeder head to come into contact with the interior of the fountain pen cap, so that the exterior surfaces of the fountain pen sec ion are always kept clean to prevent staining of the fingers of the hand of a person using the fountain pen.

The ink guard which is formed on the section is so positioned that the outer end thereof is free from contact with any portion of the fountain pen cap. The guard is also engaged around the feed bar and the pen point beyond thestop flange seat of the section so that the excess ink on the feed bar and the pen point is not permitted to settle on the end of the ink guard but flows into the ink guard recess, from where it may gradually flow back through the ink feed groove of the feed bar into the ink supply chamber of the fountain pen. This is a very important feature, since the excess ink at no time comesinto contact with the section stop flange or with the outer end surface of the ink guard.

It will, of course, beunderstood that various details of construction may be varied through a wide range without departing from the principles of this invention, and it is, therefore, not purposed to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
